The brain of a healthy person can heat up to 41 °C.

In other parts of the body this temperature is only in fever. The study involved 40 people 20-40 years old. The scientists measured the temperature using a new method of brain scanning. Each volunteer underwent three examinations: morning, afternoon and night. It turned out that the temperature of the brain changed in different areas and depending on the time of day, sex and age of the participants.

The source of new antibiotics has been found in ocean plastic.

Oceanologists and biologists have found five types of bacteria that produce antibiotics from plastic thrown into the sea. Natural antimicrobials have tackled widespread bacteria and two resistant strains. Among the new sources of antibiotics are Bacillus, Phaeobacter and Vibrio strains of bacteria.

The climate crisis has already threatened half of humanity.

People need to cut their emissions by 45% over the next decade and then reach net zero by 2050 to keep global warming below the 1.5°C threshold. This was stated by UN Secretary General António Guterres during the Austrian World Summit. “The window of opportunity to prevent the worst effects of the climate crisis is rapidly closing. Our planet has already warmed by 1.2°C. Let me be clear: national commitments are not enough. While the authorities of many countries are playing for time, inaction leads to dire consequences. Climate change is already being felt and about half of humanity is in the danger zone,” said Guterres

First orbital flight.

Elon Musk said that the first orbital flight of the prototype Starship spacecraft could take place in July this year. Also, the second stack - B8 and S25 - will be in flight readiness in August, and subsequent pairs of the ship and the booster - every month. However, experts suggest that the dates may change.

In Siberia, cats and dogs were cured of cancer for the first time in the world at a neutron accelerator.

Russian scientists for the first time in the world cured cancer by boron neutron capture therapy (BNCT) of large mammals - cats and dogs. They were irradiated at the accelerator neutron source. 15 animals participated in the tests. Initially, the animals received a targeted delivery of boron. Then they were put into a medical sleep and irradiated for two hours. During the procedure, scientists monitored the physiological parameters of the animals. After irradiation, the tumors in cats and dogs decreased, and their general condition improved.

Cybersecurity researcher Martin Herfurth learned how to hijack a Tesla in 130 seconds.

It is in this period of time that you can start the car after opening the door with a key card. Herfurt noted that during this period, the electric car can accept new keys via Bluetooth. He created an application that intercepts the signal and allows you to create your own key, and then download it to the car - it is enough to be near the victim during that very 130-second window. The researcher has already transferred the information to Elon Musk's company.

A Google programmer noticed signs of intelligence in artificial intelligence.

Google has temporarily suspended software engineer Blake Lemoyne, who concluded that the artificial intelligence (AI) created by the company LaMDA has its own consciousness. According to journalists, the developer monitored whether the chatbot uses discriminatory language. However, in the course of this task, the specialist began to become more and more convinced of the idea that AI has its own consciousness and perceives itself as a person. “If I didn’t know for sure that I was dealing with a computer program that we recently wrote, then I would have thought that I was talking to a child of seven or eight years old, who for some reason turned out to be an expert in physics,” Lemoyne noted.

Angel Alvarado, 19, set the world record by solving three Rubik's Cubes in 4 minutes and 31 seconds while juggling them.

The previous record of 4 minutes and 51 seconds also belongs to Angel.

Kombucha bacteria can survive on Mars.

An international team of scientists sent a kombucha into outer space - it was grown for a year and a half on the outside of the ISS. After that, they were returned to Earth, reactivated and cultivated for another 2.5 years. As a result of the experiment, the microbial ecology of kombucha cultures was disturbed. But the cellulose-producing bacteria Komagataeibacter survived. This means that bacterial cellulose is most likely responsible for the survival of microorganisms in extraterrestrial conditions. That is, it can serve as a biomarker for alien life. Also, on the basis of bacterial cellulose, it will be possible to make a protective layer on items needed by the future space colonizer.

Microplastics were first found in the fresh snow of Antarctica.

Prior to this, particles were found only in sea ice and surface water bodies of the continent. Microplastics were present in all 19 samples taken from the Ross Ice Shelf. On average - 29 particles per liter of melted snow. This is more than in the nearest sea and ice. Near the bases of polar explorers, the concentration of microplastics was even three times higher. Scientists have found 13 different types of plastic. The most common is PET. They make bottles and clothes from it. Microplastics could have entered Antarctica by air from other parts of the world, or they could have been brought to the continent by research teams.

In China, a man taught his husky Lucky how to cook while he is away

Through a remote home monitoring system, the owner asks the pet to turn on the slow cooker, in which he put rice before leaving.

That's the memory!

Horses have great memories. They can remember the offender for life, but they also do not forget their friends.

Importance of coffee in Yemen and Arabia.

Initially, coffee was considered in Yemen and Arabia as a miraculous medicine and was consumed only on the advice of a doctor. Many viewed it as a brain tonic or as a way to stimulate religious visions.

About tigers.

The skin of tigers is actually striped, just like their fur. In addition, no two fur colors are the same.

Zipline taught drones to hear planes and avoid collisions with them.

The company has developed an acoustic system for detecting other aircraft for drones. It uses microphones and allows you to detect other devices within a radius of two kilometers, as well as automatically rebuild the flight path to avoid a collision.

The Stargazer plane will take passengers from Japan to the United States in just an hour.

Aerospace startup Venus Aerospace presented a visualization of its future Stargazer hypersonic aircraft. Its advertised speed is about Mach 9, which allows the crew and a small number of passengers to get from Tokyo to Los Angeles in just one hour. Stargazer will take off using engines, but when it reaches the edge of space at an altitude of 52 kilometers, it will switch to "rocket mode". The plane is designed to carry 12 passengers, and its speed exceeds 11,025 km/h, which is almost 9 times the speed of sound.

In Saudi Arabia, they decided to invest a billion dollars annually in the development of life extension technology.

The Saudi royal family has decided to invest a billion dollars annually in the Hevolution Foundation, a non-profit organization. She is looking for methods to combat aging and develops life extension technologies. The royal family's money will make the Hevolution Foundation the world's largest funder of aging research. The organization will distribute grants for the development of anti-aging drugs and clinical trials. It is expected that researchers will find a means to delay the onset of diseases, which will be available to the masses.

People are born with moral guidelines already built in.

These conclusions were reached by Japanese psychologists in the course of experiments with eight-month-old children. The kids were shown on the computer screen an animation with two multi-colored balls. One of them offended the other. In another video, a stone was falling on a ball. The children were able to control the computer system using eye-tracking technology. When they had the opportunity, they sought to punish the aggressor ball and drop the stone on it. It turned out that infants who still cannot talk were punishing the antisocial aggressor. This indicates that humans may have developed a tendency toward moral behavior over the course of evolution.

Unsociable people have a higher risk of dementia, scientists say.

They came to this conclusion when they analyzed neuroimaging data from more than 30,000 people from the UK Biobank. Scientists have found that socially isolated people have less gray matter in areas of the brain responsible for memory and learning. Next, the researchers used modeling techniques to explore the association of relative social isolation and loneliness with cases of dementia. After assessing other risk factors, such as chronic diseases, lifestyle, and the presence of depression, scientists found that people who are unsociable are more likely to develop dementia by 26%.

In Britain, robots appeared - waiters.
